At the Battle of the River Berre in 737 Frankish forces under the command of Charles Martel intercepted a sizeable Arab force sent from Al-Andalus and led by Uqba ibn al-Hayyay to relieve the siege of Narbonne. The battle, which took place at the mouth of the River Berre (now in the Département of Aude), was a significant victory for Martel in the campaigns of 736-737. During this period Martel effectively prevented greater Umayyad expansion beyond the Pyrenees.
